Bonus points

could someone show me any material that shows how bonus points are calculated on this site, I get the 10 point bonus if you get a point but sometimes I get these big bonuses and I am unsure how I have achieved this.

"Additionally, you'll get up to 500 bonus StrategyPoints for your PokerStrategy.com status.
For your first deposit, you will receive at least 100 bonus StrategyPoints, giving you you instant Silver status and access to advanced strategies and training materials. In case your first deposit exceeds $100 you will get 1 bonus StrategyPoint (up to 500) for every dollar making it easy to reach even Gold status."

This is the same for each room that offers the 500 SP bonus.

I hope that's what you wanted to know but if not, give us another shout
